Pyeclib

------------

* Eliminate spurious syslog messages and added cleaner
mechanism for querying all available backends on a system.

* Moved source code hosting from bitbucket to Openstack infra.
This is first release with Openstack Infra

------------

* Remove integrated liberasurecode - the prereq library is now
available in major deb/rpm based distros

* Eliminate liberasurecode-related rpath checks, library searches
and architecture validation

* Changes for compatibility with liberasurecode versions prior to
1.1.0

* Make VALID_EC_TYPES a runtime property - dynamically look for
liberasurecode EC schemes available at runtime

* More comprehensive unit test coverage

* Add travis-ci build config for automated build/tests

------------

* Eliminate pyeclib dependency on alloc functions internal to
liberasurecode

* Update include subdirs to be explicit

* Update internal liberasurecode version to 1.1.0

------------

* Eliminate rpath handling in setup.py

* Clean py34 shared libraries created during build

* Fix integer truncation issue with PyBuildValue on Big Endian
systems by explicitly casting the size argument passed in to
Py_ssize_t. Also fix import issue with the API test where
older versions of Python fail to import.

* Add --install-liberasurecode option to setup.py. Requested
by Red Hat/Debian package maintainers.

* Update bundled liberasurecode version to 1.0.9

------------

* Support for a new Reed-Soloman backend (liberasurecode_rs_vand)
- naive, non-accelerated version, native to liberasurecode

* Single version, with liberasurecode distributed in the package,
installed if necessary. No versions going forward with Jerasure
included. Use 'liberasurecode_rs_vand' for default test backend.

* Test code refactor for eliminating duplicated code, add cases
for liberasurecode_rs_vand and making jerasure/isa_l test cases
conditional.

* Better Python3 support

* setup.py enhancements
- improved library path detection on Mac OS X (and Linux) including
workarounds for Mac OS X dyld bugs for library search paths
- handling installroot better for optional liberasurecode installs

* tox support for automated py27 and py34 testing
